Simplify the post-install test targets.

Remove the implicit `make install` from the post-install test
targets. Users can run `make install install-test` if required.

         Run the test suite continuously on change. This is equivalent to
         manually running `make test` when a source file is modified. Note that
         `make install-test` tests are not run. This requires bazel-watcher.

+    make install-test
+        Run the full test suite against an installed CompilerGym package. This
+        requires that the CompilerGym package has been installed (`make
+        install`). This is useful for checking the package contents but is
+        usually not needed for interactive development since `make test` runs
+        the same tests without having to install anything.
